MOLD FOR THE MANUFACTURE OF BRICK.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed March 20, 1916. Serial No. 85,368.

To all whom it may concern Be it known that I, EDWARD NEW, a subject ofthe King of Great Britain, residing at Hamilton, in the county ofWentworth, in the Province of Ontario, Canada, have invented a new anduseful Mold for the Manufacture of Brick, of which the following is aspecification.

My invention relates to improvements in molds for the manufacture ofbrick, whereby the brick is molded with longitudinal ridges on thebottom thereof.

The invention consists essentially of a brick mold having longitudinalvents or airspaces in the bottom thereof at a suitable distance from thejunction of the bottom and sides of the mold.

The objects of the invention are, first, to provide means to producebrick having straight, true andwell-defined edges, and second, toprovide means to protect said edges of the brick from chipping in thehandling thereof.

Hitherto, the air-spaces were at the junction of the bottom and sides ofthe mold, resulting in uneven edges on the brick, which edges werefurther damaged and chipped in the handling of the brick before andafter burning. As can be plainly seen in my invention, the said ridgesbeing a distance from the sides of the brick, act as buffers andseparate the sides and edges of the brick one from the other when thesame are stacked or in transportation.

I attain these objects of my invention by the device illustrated in theaccompanying drawing, in which Figure 1 is a sectional end elevation ofmy improved brick mold showing one way of constructing the same, and asseen through the line 2-2 in Fig. 2 of the drawing, adjacent and similarmolds being broken away; Fig. 2 is a plan of Fig. 1; Fig. 3 is asectional end elevation of the mold showing another method ofconstruction, and as seen through the line 1-4 in Fig. 4:, adjacent andsimilar molds being broken away; and Fig. 4 is a plan of Fig. 3.

Similar letters refer to similar parts throughout the several views.

The bottom A and the sides B and C constitute the body part of one of aseries of molds. As is well known to those skilled in the art of brickmanufacture, the series of molds consists of from four to seven molds orcompartments, more or less as the case may be. 1

D is'the usual projection on the bottom of the mold for the purpose offorming the centrally located recess in the brick, and commonly lmown asthe stock.

In the method of construction shown in Figs. 3 and 4 of the drawing, Iuse a metallic bottom wherein the aforementioned projection D is formedduring the mechanical shaping of said bottom, while in. the constructionportrayed in Figs. 1 and 2 of the drawing, a wooden bottom is used, theprojection D being rigidly secured thereto and forming a part thereof.The use of said projection is old and does not form part of myinvention.

E are longitudinal air-spaces or vents in the bottom of the mold,extending nearly the full length thereof, and situated at a distancebetween the sides of the mold and the projection D. In Fig. 4:- of thedrawing, these vents are in plural or multiple form in order that astock die may be used in punching the vents from the metallic bottom ofthe mold, although the longitudinal single slot may be used if desired,as in the bottom shown in Fig. 2 of the drawing. The situation of thesevents or air-spaces E is the important feature of my invention, as theold method was to have the air-spaces at the junction of the bottom andsides of the mold. This caused the brick to have uneven edges. In Fig. 1of the drawing, the said airspaces or vents E gradually widen out towardthe under surface of the bottom A, in order that the possibleaccumulation of clay which has passed through the vents E may be easilyejected or shaken therefrom.

In Fig. 3 of the drawing, I reinforce the metal bottom A with a woodenstrip F, each end of which strip is rigidly secured to the under surfaceof the sides C of the mold.

The sides of the metallic bottom A shown in Fig. 3 of the drawing,extend a suitable distance under the sides B of the mold, and areclamped thereto with wooden strips H, which strips are rigidly securedto the under surface of the sides B by means of screws 2.

The sides of the strips H and F which are nearest to the vents E arebeveled so as to form a suitable exit for a possible accumulation ofclay between the same.

By using my method of locating the airspaces at a distance from thesides of the mold, the edges or corners of the brick are left even,sharp and well-defined, and the ridges or bars caused by the inclinationof the clay to pass downward through the said air-spaces or vents E Whenthe soft clay is pressed into the mold, a portion of which clay remainson the bottom of the brick forming said ridges, tends to separate thebrick one from the other when they are stacked or in transportation,thereby eliminating the further possibility of the corners becomingchipped, ragged and uneven.

By the elimination of the projection or stock D on the mold, the bricksmay be made Without the recess if desired.

Minor changes in the construction of the mold may be had Withoutdeparting from the spirit and scope of my invention.

I claim In a brick mold of the character described,

the combination of sides and ends, of a bot- In testimony whereof, Ihave hereunto aflixed my signature before the undersigned Witnesses.
